01-08-2013  The results presented in Fig. 8 show that the distribution of As, Pb and Zn in the blister decreased when the dust addition ratio increased. The presence of multiple phases enhances the elimination of Pb and Zn. During the second stage of converting, the vapor pressure of As species is low and for that reason the volatilization decreased.

The Arsenic Rule - US EPA

• Arsenic is also released from a variety of human activities. Almost 8 million pounds of arsenic and arsenic containing compounds were released into the environment in 1997. • Arsenic is found in the preservative chromated copper arsenate (CCA) used to preserve wood. 90% of all arsenic consumed in the U.S. is used in the production of CCA.

Abstract. Studies on the production of L-arginine by fermentation using mutants of Corynebacterium (Brevibacterium), Bacillus, and Serratia have been conducted since the 1960s. More recently, the breeding of L-arginine production strains by gene recombination techniques using Escherichia coli has been investigated. To produce L-arginine efficiently by fermentation, it is necessary to breed ...
